Common Concerns – Solved
"Will this sync automatically with the correct time?" Yes — this movement is designed to receive the DCF77 radio time signal broadcast from Germany, which covers most of Central Europe. It is not compatible with other regional time signals such as WWVB (US).

"Does it come with a battery?" No, it requires 1 AA battery, which is not included in the package.
